WILLIAM GREEN, OF BALTIMORE, MARYLAND.

WINDOW-BRACKET.

Application filed April 7, 1917.

To all whom it may concern:

Be it known that 1. WILLIAM GREEN, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented new and useful Improvements in lVindow-Brackets, of which the following is a specification.

This invention relates to a window bracket or self supporting means, and one object of the same is to provide a device of this class that may be easily applied to window frames of various dimensions above a window sill and held in positively fixed applied position and also to include in the general structure means whereby the shelf supporting parts may be adjusted to accommodate window sills of varying width and also to compensate for inclinations of the upper surfaces of sills and maintain the shelf supported by the bracket, arms or members in true horizontal position. The improved window bracket is adapted to support various articles, uch as window boxes, window gardens or other containing devices, and at times parts of the bracket maybe used as means for holding handled article or containing devices.

The bracket is easily applied to any window frame and sill and the several parts may be readily constructed and associated.

The invention consists in the construction and arrangement of the several parts which will be more fully hereinafter described and claimed.

the main attaching member and showing a portion of the window frame also in section.

The improved window bracket embodies essentially a main attaching member 5, two connecting arm 6, two supporting and retention arms 7, and two extension arms 8. The attaching member 5 comprises a metal tube 9 open at opposite ends and having securing rOds 10 movably mounted therein and projected from opposite ends thereof. The outer terminals of the rods 10 are formed with heads 11 provided with teeth or serration 12, and extending longitudinally into each head and in central relation thereto is a socket 13. The inner ends of the rods 10 are reduced, as at 1 1, and thereovcr are fitted the opposite ends of a coiled spring 15 mounted in the tube 9, a shown by Fig. 2, and retained in central position by a pin 16 extending transversely through the tube and the spring and which operates to prevent the spring from shifting either to the right or left or from a predetermined applied position. The spring 15 exerts considerable tension on the rods 10 and operates to force the aid rods outwardly. The heads 11 cooperate with studs 17, as clearly shown by Fig. 7, each stud being tubular and having a flanged base 18 with a serrated or toothed face 19 to engage the wood of the side of the window frame, each stud being fixed to the window frame by a screw 20 inserted therethrough. hen the screws 20 are inserted through the studs 17 the serrated or toothed faces 19 of the bases 18 are brought into firm engagement with the window frame sides and the studs are thereby prevented from turning or shifting out of applied position. The serrations or teeth 12 of the heads 1.1 of the rods 10 engage the inner faces of the bases 18 and the attaching member 5 as a whole is thus prevented from rotating on the studs.

The connecting arms 6 each have a flat extremity 21 which is inserted through a slot 22 in the rod 10 near the outer end of the latter and is held in fixed position relatively to said rod by a set-screw 23. The arms 6 are similarly associated with and adjustable in the rods 10 without in the least interfering with the movement of the rods 10 in adjusting the attaching member 5 relatlvely to various widths of window frames, and the said attaching member 5 may be readily separated from the connecting arms 6 by releasing the set-screws 23 when 1t 1s desired each supporting or.

to arrange the parts of the bracket in compact form. Each connecting arm 6, also has;

a vertically disposed hanger 26 intersecting the attaching extremity 21 at a right angle, and from the lower portion of the said hanger 2G a horizontal member 27 extends outwardly and intersects the hanger at a point slightly arm 32 being of such thickness as to have its lower face flush with the lower edge of the stop or abutment 28. The arm 32 also has an outer shoulder or abutment 33 with which the outer end of the arm 27 engages when retention arm 7 is closed 1 horizontal. arm 27 of each in relatively to the connecting arm 6. Each supportingor retention arm 7 also has a depending arm 3a intersecting the arm 32 at right angles, the arm 34 serving to engage over and bear against cordance with building structures. The arm 32 with the arm may be readily adjusted on the arm 27 the pin 29 sliding in theslot 31, and to separably associate the arms 27 and 32 the slot 31 has an inner enlarged extremity 35 which is large enough to permit the clearance of the head 30 of the pin 29 therefrom. To prevent displacement of the arm 32 and its correlative arm 3% the said arm 32 has upwardly projecting side lugs 36 which engage the opposite edges ofthe arm 27, and by this means the said arm 32 will be prevented from shifting sidewise in relation to the arm 27. i

. The extension arms 8 are adjustably'held by the depending arms 34L of the supporting and retention arms or-niembers 7, a'ndeach arm has aseginent 37 projecting outwardly therefrom. Each segment 37 is suitably secured to the arm 3a and is provided with notches 38 in its outer edge which are adapted to be movably engaged by a pin 39 secured to and projectingfrom an inner angular head 4:0 formed as a part of each extension arm 8.. Adjacent to the pin.39 the gaged shifted so. as to head 40 is also formed with an elongated slot ll extending transversely thereof and en by-a clamping screw 4C2 whichextends into the segment 37 andby means of jwhich the-extension arm may be loosened and p I I change the position of the pin 39relatively to the notches 38- and whereby eachex tcnsion arm 8 maybe adjusted relat -vely to a horizontal plane tecompensate a for inclinations of the upper surface ofthe w 1nd0 w sill orle ge 1. 1 011 Whichthe arms32 and 27 are disposed and thereby provide for shelf d-3will depend upon. the

dow sill or ledge and the outer face or edge of a sill or ledge of a brick wall which may vary in acav shelf Ofronsiderable width,

sion arms 8 may a horizontal support of a self l3, as shown by dotted lines- The outer end of each arm 8 has an upwardly projecting stop or guard Hto bear against the outer edge of the shelf 43. It will be seen that the width of the width of the sill or ledge on which the arms 32 and 27 are disposed, the para.- as shown in Figs. 1 and 3, for instance, haying a minimum adjustment or being fully contracted. Whenthe arms 32 are adjusted or shifted outwardly relatively to the arms'27 to compensate for varying idth's of window sills or ledges the extension arms 8move equally 111 2111 outward d1- rection and as a consequence the distance between the vertical members 26 of the connecting arms 6 and the guards 4A; of the extension arms will be greater and a larger shelf may be disposed thereon or be used in all. cases and the outer edge thereof pushedout into engagement with the guards l i. The depending or vertical arms 3i of the supporting and retention arms 7 bear against the'outer edges or faces of the winmaterially brace the structure, and particularly the extension arms 8, and permit considerable weight to be imposed on the outer part of the shelf a3. engaging the said arms. The adjustable features of the several parts of the bracket which are utilized directly for supporting the shelf 43 make it possible to provide for vith ad vantages in window bracket constructions, as more area or space is provided upon which to dispose containing or. otherarticles. At any time desired the shelf 43 may be removed and under such conditions the extenbe adjusted so as to depend from' the segments 37, and the lower edges 45 of the heads 40 may be brought to bear against the outer surfaces of the depending or vertical arms 3% and be held fixed by the clamping screwsv 42, and unde'r'this adjust ment ofthe extension arms the guards a l upon which the bails or may serve as hooks basket's'and other articles handles of buckets, may be applied.

All the parts of the improved bracket are constructed of suitable metal and may be treated to render the same non-corrosive, and

owing" to the simplicityof the connections between the parts they may be readily detached or assembled and may also be economically.manufactured and sold at a comparatively small cost. The improved bracket will be found exceptionallynseful and advantageous, and it willbe; understood thatit is.) intended to; b ap 1-iednot only to windows, but 'tq other structures where it may be found appllcable'and'where ashelf maybe needed. Y What is claimed is:
